Description

A funny and energetic girl and Reyla's older twin. Probably the group's closest to a normal girl, if a normal girl goes following her friends on dates while wearing a giant squirrel costume in the middle of the summer. She works in her parent's american style diner Cherry Crown Diner as waitress and poster girl. She and her sister are best friends with Corona, Ramune and Luna. Every school morning she and her sister bring breakfast to them, usually by throwing the food at them.

She's very honest and pure, which is why she's called Crystal Heart, contrary to her sister, who is mysterious and seems to be always be planning something. When Ramune is not around or not able to make the tsukkomis, Iris is the one to take up the task.

She loves Luna, but also loves the group, and doesn't wants the group to disband because of a fight for Luna's love. When her sister proposes the "Harem Plan", she agrees happily, as long everyone on the group is happy too.
